& Of of fu l improvements in Loch Valves, of which the following is :i specification.

This invention relates to automobiles and other motor vehicles and has for its principal ob ect the provision of simple, inexpcn sive and efficient means for preventing uny I T115111 is such as to-look the shaft only when the letter is 111 valve closing position and authorized use o'ft'such vehicles.

L h I n a further ob ect of the invention is to attain the above mentioned result by the provision of lock controlled means for 010s ing the fuel passage through the manifold of the engine to shut off the fuel supply from the carburetor.

The foregoing and other objects of the invention, as well as the particular novel details of construction, combination and arrangement of parts herein disclosed Will be more readily understood from the following description and cmooompanying drawings.

In the drawings,

Fig. 1 is a fragmentary side view of an automobile partly broken away to disclose the application of my invention thereto.

Fig. 2 is a longitudinal section view of a valve casing constructed in accordance with my invention, the valve and certain parts associated therewith being shown in elevation.

Fig. 3 is s transverse sectional view on the line 8-3 of Fig. 2.

Referring more particularly to the drawings, 5 designates an automobile of conventional construction, including the usual dash board 6, engine 7, intake manifold 8 and carburetor 9.

In accordance with my invention. as herein illustrated. a valve casing 10. containing e butterfly-valve 11, is inserted in the intake manifold 8 to control the passage of "fuel from the carburetor 9 to the engine 7. The valve spindle 12 is fitted at one end in a. bearing opening or recess 13 provided in the casing and is provided at the opposite end with a cross slot I l receiving therein e cross key or rib 15 formed on one end of a flexible actuating shaft 16. As shown, the keyed end of the shaft 16 extends into an offset chamber 10' formed integral with the casing 10 end is enlarged to form e shoulder 17. A guide or bearing block 18, surrounding the shaft 16 within the chamber 10', is

Serial Flo. 59-..,3S4l.

confined between tl c said shoulder and the top wall oi the chamber-end tllfliEbf-l serves to prevent displacement of the key 15 from the slot 14.

As shown to advantage in 1, the flexible shaft 16 extends from the casing 10 or valve spindle 12 to a casing 19, csrried by the cash board 6, and containing a suitable key-controlled locking mechanism connected with and controlling the actuation of said shaft. Prefcrablv the locking mechaslso serves ass means by which movement of the shaft i efi'ected to open or close the valve.

Thstportion of the shaft 16 extending between the casings l0 and 19 is preferably enclosed in a hollow tube 20 secured at one end to the casing 19 and having the opposite end secured in a recess 21 formed in the outer end of a tubular extension 22 formed integral with the block or bearing 18.

lin order to provide for the mounting of the valve 11 and its spindle 152 within the casing 10, the letter is made up of two semicylin rical sections 23 and 2e, soldered or otherwise held together and having their meeting edges shaped to provide e lap or slip joint 25. The ends of the sections 23 and 24 be externally threaded for engagement with the sectionso'l the manifold between which the casing 10 is interposed, but this is offered merely as a suggestion, as the casing 10 may, obviously, be secured in place in a variety of ways other than that specified.

in the use of the device, it will be apperent that movement of the flexible shaft 16 to valve closing or opening positions is eilected by inserting at key in the casing 19 and turning it in the proper direction. When the key is tur cd to move the spindle to valve closing position the locking mechanism within the casingli) acts automatically to secure the shaft in such position so that when the key is removed. unauthorized use of the engine willbe prevented owing to the fact that no fuel can be fed from the carburetor to the intake valves.

For convenience, I prefer to locate the locking mechanism controlling the actuation of the velve spindle 19;, on the dash board 6, but it will be understood that this is not absolutely essential as the flexible shaft 16 may be eliminated end the locking mechanism so sirable, providing, of course, that the same come within the scope of the appended claims and that they do not depart from the spirit of the invention.

VVhatI claim as my invention is: V

1. A device of the class described comprising a valve casing provided with an offset chamber communicating therewith, a valve in the casing, a guide block in the said chamber, a flexible sh aft extending from the valve outwardly through the guide block, and means for actuating said shaft.

2. A device of the class described comprising a valve casin provided with an 05- set chamber communicating therewith, a valve in the casing, a guide block in the said chamber, a flexible shaft extending from the ee s-1o valve outwardly through the guide block, and a locking mechanism controlling the actuation of said shaft.

3. A device of the character described comprising a valve casing, a butterfly-valve therein including a spindle, one end of the spindle being journaled in the wall of the casing and the other end being provided with a cross slot, a flexible shaft having one end extended into the casing and provided with a cross key fitting into said slot to es tablish a drive connection between the spindle and shaft, the keyed end of the shaft being enlarged to afford a shoulder and a guide block confined between said shoulder and an opposing wall portion of the casing and affording a bearing for the shaft.

4. A device as recited in claim l including locking mechanism connected with and controlling the actuation of the said shaft.

in testimony whereof I hereunto affix my signature.
